A bootable CD normally contains an image of a bootable floppy, so you
create a bootable floppy containing the files you want, and then tell your
CD-burning program to use that floppy as the boot image for the
CD.  Alternatively, if you're doing this semi-frequently, you might want to
copy the image of the floppy to an image file on your hard drive, and then
create the bootable CDs from there.

Creating the image file varies in difficulty, depending on the OS you're
using to do it.  Under Linux, the proper incantation of dd should do it
from a normal command line.  Windows NT/2K/XP don't (TTBOMK) include a
utility to do it, but writing one is pretty simple: you open a file named
"\\.\A:" and read from it in chunks that are multiples of the sector size
(though the name is different, the same basic idea will work under Linux as
well). Under DOS, you can read with int 25h; most C compilers for DOS have
front-ends for this.  If you prefer to use a front-end that's independent
of the compiler,  I believe there's one in Snippets.
